Find the LCM of 6 and 15.<br> A) 6 <br> B) 15 <br> C) 30 <br> D) 90
erastovalidia [21]

Answer:

30

Step-by-step explanation:

the answer is 30 because if you count by 6 it would go 6,12,18,24,30,36,42 and if you go by 15 it would be 15,30,45,60,75,90..... and the only number that you see twice is 30 so the answer would be 30. Hope this helped...

What is the range of this piecewise function
White raven [17]

Answer as a compound inequality: -4 \le y < 2

Answer in interval notation:  [-4, 2)

=============================================

Explanation:

The range is the set of all possible y outputs of a function. When dealing with a graph like this, we just look at the highest and lowest points to determine which y values are possible.

The lowest point occurs when y = -4. We include this value. So far we have y \ge -4 which is the same as -4 \le y

The upper ceiling for the y value is y = 2. We can't actually reach this value because of the open hole at (-3,2). So we say that y < 2

Combine -4 \le y and y < 2 to get the compound inequality -4 \le y < 2

This says y is between -4 and 2, including -4 but excluding 2.

To convert this to interval notation, we write [-4, 2) where the square bracket says to include the endpoint and the curved parenthesis says to exclude the endpoint.

The scale on a map shows that 1 inch = 30 miles. If there are 4.5 inches between your present location and the place you want to
anastassius [24]

Scale : 1 inch = 30 miles

So, the ratio between the distance on the map and the real distance is 1:30

When a quantity increase/decrease in a ratio, the other one increase/decrease respectively.

Call the miles we have to go : x

1:30 = 4.5:x

(1x4.5):(30x4.5) = 4.5 : x

4.5 : 135 = 4.5 : x

So, x = 135 => We have to go 135 miles to get to the place we want to go.

Two events, A and B, are independent of each other. P(A)=– and P(A and B)
Georgia [21]

Answer:

D: 0.75

P(B) = \frac{6}{8} = 0.75

Step-by-step explanation:

<u>Explanation</u>:-

<u><em>Independent events:</em></u>

If the occurrence of the  event 'B' is not effected by the occurrence or non- occurrence of the event 'A' then the event 'B' is said to be independent of 'A'

or

<em>The two events are independent if the incidence of one event is not affect the probability of other event.</em>

<em>P(A∩B) = P(A) P(B)</em>

Given data A and B are independent events

Given  data

    P(AnB) = \frac{1}{8} and P(A) =\frac{1}{6}

we know that A and B are independent events are

  P(A∩B) = P(A) P(B)

  \frac{1}{8} =  \frac{1}{6}  P(B)

Now calculation we get

P(B) = \frac{6}{8} = 0.75

<u><em>Final answer:</em></u>-

P(B) = \frac{6}{8} = 0.75
